Liquid pail



July 9, 1940. E. w. VON KNAUF LIQUID PAIL Filed May 26, 1938 Patented July 9, 1940 UNITED STATES PATENT orrlca 3 Claims.

This invention relates to a pail such as used for paints and other liquids with'which brushes are used.

It is well known that the ordinary paint cans having removable lids, are formed with channels which quickly become filled and clogged with accumulations of paint or other liquid deposited by a brush or the like and unless this liquid is removed in some manner, it becomes wasted and frequently hardens so as to interfere with the proper replacement of the lid.

An object of the present invention is to pro- -vide the lid-receiving channel of 'a paint can or the like with drain openings so located that any 5 liquids deposited in the channel will be returned by gravity to the can.

It is a further object of the invention to so locate the drain openings that they will be tightly sealed by the lid when in position, thereby avoiding all danger of evaporation or leakage.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a plan view of a can having the present improvements, a portion of the removable lid being broken away.

Figure 2 is an enlarged perspective view of sections of the lid and can separated.

Figure 3 is a similar view showing said sections seated one within the other so as to seal the drain 4o openings.

Referring to the figures by characters of reference I designates a can provided at its top with a ring 2 in which is formed a depending circular channel 3. This channel is deeper than it is wide and has its walls converging downwardly to a transversely rounded bottom as shown. The upper edge of the inner wall 4 of the channel terminates in a reenforcing bead or roll 5 turning outwardly from the channel and this wall is also formed with a series of drain openings 6 which can be of any desired shape and are located slightly above the bottom of the channel.

That portion of the ring 2 between the channel 3 and the wall of the can I is preferably curved inwardly and downwardly toward the channel to a slight extent as shown so that any liquid deposited on the ring will tend to drain toward the channel.

The cover I is of the usual construction with the exception that, in addition to the marginal 5 reenforcing head 8, it has a deep wedging channel 9 so proportioned as to wedge tightly into the channel 3 and to form two metal sealing contacts with both walls of channel 3 and with the bottom of said channel, as shown particularly 10 in Figure 3.

After the container has been filled with paint or other liquid, the cover is placed thereon and forced downwardly, the channelled portion 9 being wedged into the channel 3- so that the parts 15 are thus tightly sealed together as shown. The cover is removed in the usual way by prying it upwardly with a suitable tool inserted between the marginal portion of the cover and the corresponding portion of the container. While the 20 can is in use any paint or other liquid accumulating on the ring 2 or on the top edges of the channel walls will drain downwardly into the channel and thence through theopenings 6 back into the can. Thus the cover can be readily replaced 25 on the can whenever desired and a tight sealing action can be effected so as to prevent evaporation of the contents of the can or oxidation thereof.

Importance is attached to the fact that the 30 channel portion 9 acts as a wedge which not only seals each of the openings 6 so that they are cut off from communication with the interior of channel 3 but also forms at least one continuous annular sealing contact with the outer 36 side wall of the enamel 3 and also a continuous sealing contact with the bottom of said channel.

In other words a triple seal is formed by the use of a structure such as herein described. What is claimed is: 4o

1. The combination with a container, of a ring extending within the top thereof and provided with a channel having downwardly converging walls joined by a transversely rounded bottom, there being a plurality of apertures in the inner 45 side wall of the channel constituting drain openings, said apertures being located above the level of the bottom of the channel, and a cover having a depending circular channel portion proportioned to wedge within the channel in the ring 50 and form a triple seal by frictional contact with the apertured wall, the bottom, and the other wall of the channel.

2. The combination with a container, of a ring extending within the top thereof and provided 55 with a channel having downwardly converging walls joined by a transversely rounded bottom. there being a plurality of apertures in the' inner side wall of the channel constituting drain openings, said apertures being located above the level of the bottom of the channel, said bottom being imperforate, and a cover having a depending circular channel portion proportioned to wedge within the channel in the ring and provide a triple seal by frictional contact with the apertured ,wall, the bottom, and the other wall of the channel, that portion of the ring between the channel and the margin of the container being in- Jclined downwardly toward the channeL 3. The combination with a container, of a ring extending within the top thereof and provided with a channel having downwardly converging walls joined by a transversely rounded bottom.

the inner wall of the channel having an integral reinforcing bead extending away therefrom, there being a plurality of apertures in the inner side wall of the channel constituting drain ,openinss. said apertures being located above the level of the bottom of the channel and said bottom being imperforate, and a cover having a depending circular channel portion proportioned to wedge within the channel in the ring and provide a triple seal by frictional contact with the apertured wall, the imperforate bottom, and the other wall of the channel, thatportlon of the ring between the channel and the margin of the container being inclined downwardly toward the channel, said cover having a portion between its margin and'its depending channel for intimate contact with the inclined surface of the ring.
